I am a maker from overseas. I think you might try my track, like this one(2004 XD):

I am recently creating a new project, using the old way, i.e. ZM1.07, CityToolKit, and I found the game runs very lag. Probably 8-10 fps in multiplayer mode (But 60 fps in Race Mode!). I know I should use a better method to create thistrack but the method didn't work for my track, it is far more compilcaited.

Here's come a question, any method to make the game smoother? Any method to breke into pieces besides cutting pkg? Plz advice
